[1.9.4] NPE client crash with Botania "Key of the King's Law"

[klangg]

Reproduce:
forge-1.9.4 - 12.17.0.1954
spongeforge-1.9.4-1954-5.0.0-BETA-1418
Botania-unofficial.r1.8-308
Baubles-1.9.4-1.2.1.0 (required by Botania)

Obtain a Key of the King's Law and a Mana Tablet
Hold down the Use Item button (right mouse), with the Key in hand, until it is drawn back like a bow being fired.
Some projectiles will be fired that will explode on contact with any entity or block.
A collision results in an explosion that damages entities but not blocks.
Upon exploding all clients that can view the event have a client crash.

Client crash report, client log, and server log

If the chunk does not stay loaded the client will continue to crash everytime the player reconnects.
This happens in both single- and multi- player.
If spongeforge is removed everything works as intended.

Please let me know if you want more data or if a Botania bug report is needed.

Thanks!
